Application September 12, 1949, Serial No. 115,140 l f 3 Claims.

This invention relates to pouring regulating spouts for bottles, and particularly to a spout, in which the volume of liquid flow can be lprecisely regulated by easy manipulation in the ordinary operation of pouring, and still be instantly subject to full capacity flow.

Bottle Stoppers and pourers have been devised, but there is still lacking a pouring spout, which permits of full capacity ow although precise regulation of flow is instantly obtainable, by easy manipulation in the ordinary operation of pouring. Stopper' caps, with small tubes inserted through same, have been used. These provide refinement in the volume of liquid iiow, according to the smallness of the tube, but do not permit of yany larger volume of flow. It is evident that use of same is too time consuming, and does not meet the needs in dispensing liquors or preparing medicines and chemicals. One type of spout has been devised for dispensing a certain quantity of chemical, like nitrate of silver for photographic work. This consists of a tube with a chamber enlargement at its extremity, including a lid and with an upward bend in the tube leading to the chamber. The chamber is filled by tipping up the bottle, and then by holding the bottle in hcrizonal position, the liquid oWs back into the bottle, except that which is in the chamber, By opening the lid, this measured amount is released. This device is limited to a particular use, as it must be specially formed to dispense the certain lamount desired. Improvements have been made in stopper caps, lids, vents and sealing valves but not in a ow regulating device; permitting instant change from maximum to minimum, without refinement in manipulation. To dispense from any ordinary bottle in proper amount is difficult, requiring extremely skillful and slow handling in tilting and angling the bottle.

An important object of my invention is to provide a pouring regulating spout for bottles, in which the volume of liquid flow can be precisely regulated by easy manipulation in the ordinary operation of pouring, and still be instantly subject to full capacity ow.

Another important object is to provide such a pouring regulating spout, which can be readily applied to and removed from a bottle, and which has a closure which seats itself when the bottle is in upright position, protecting the contents of the bottle from contact with the atmosphere.

Another object is to provide such a pouring regulating spout, which can be easily cleaned and maintained in a highly sanitary condition at all times.

Another object is to provide such a pouring regulating spout at a reasonable cost.

Qther objects will be apparent from the description and appended claims.

For a full disclosure of my invention, reference is made to the description `following.and`

to the drawings, in which:

Fig. 1 is a side elevation View of my pouring. regulating spout, as it would appear if placed yony a bottle in an upright position, but -having va lportion broken away to show a sectional View of the lower portion thereof.

Fig. 2 is an elevation view, as viewediromthe right side of Fig. 1, blut with ay portion broken away to show a sectional view oi the middle portion thereof. ,l In my improved pouring lregulating spout, which is hereby disclosed, I provide it preferablyr in two sections 3 and Il, constituting respectivelyv the top and bottom portions. These portions arev to clean. The end 6 of the section 3, is for gen.-

eral use, shaped to pro-vide a round orifice from which to pour. A hinged lid I is mounted at the end 6 to normally keep the orifice closed, but to swing open for pouring and obviates the neces` sity of removing and replacing a stopper at frequent intervals for dispensing. This is accomplished because the end 6 is on the bias, and

also the section 3 has an arcuate portion 3 delinitely maintaining the lid I'in such position by gravity. When pouring, the lid 'i may also be tipped back into reverse position against thel spout. The arcuate portion 8, in addition to the purpose above stated, also facilitates in pouring, as the shape directs the liquid downward. The section 4 is provided with a round tubular shank 9, which extends through a stopper cap I0 and gives access to the contents of the bottle. The opening I3 in this tubular shank is of substantial diameter, to permit fast pouring, and normally would be of the same diameter as the orice at the end 6. The stopper clap I0 is of quite conventional construction, and consists of a cap with a downward extending brim over the neck of the vbottle and with a stopper of cork or similar material to closely t within the opening in the bottle, and the cap [and stopper perforated to closely iit over the tubular shank 9. In the middle of the device, I provide la passageway I4 of restricted Width but of such height, `that its cross sectional area is equal to the cross sectional area of the orice in the end G or of the opening I3. The devicewould still be operable even though the passageway were larger or smaller than the openings 6 and I3, and even thoiughl these open ings were not equal in area, butfcr smooth How anais@ necessarily flushing with the bottone; p ourin'glinef of the spout,'it` requires la construction with an extension Il upward from the pouring line. The

`passageway is substantially rectangular except for rounded corners, and the transition-,1. between:

it land the round tubular sections at the respece tive extremities of the spout, is accomplished by a construction tapering inwardlyto' the sides-'of the passageway and with slopngepplftions i2rinz clined upwardly to the top of the passageway.

The entire spout construction is of course--in4 symmetry about a median plane on the long axis ofxthefvpassageway; Ituisinoty necessary'to provide any vent in the device, asfth'equantities dispensed." are usuallysmalL. not requiring ingress of out-1 sideair; The-construction itself isv also conducive: to entrance.y of air into the=bottle,f resul-tingin afsmoothsflow; The' dev-icey can be made of any suitable material, but preferablyv mad-ey of plase' tic, except for a cork stopperA andf'ametal hinge pin; For clear liquids; transparent material would be preferable, but for-'colored liquids 'cere tain color combinations would be attractive;y The broadrelativelyriiat surface on each sidefofithe device, provides ample vspace-for embossin'glor otherwise aixingfa monogram, embleml ori-mark ofa manufacturer, and also for attaching `a label to' Ydenote contents ofr bottles.-

Fi'om'theoregoing it is apparent how-mypour' ing regulatingspout isy constructed and# that it' must have many ydesirable features. It provides for a smooth iiow oifliquid, and increasestliev refinement in regulation' of'v ow; Withoutv requiring any special skill in the handling ofthe bottle: By converging the flow from the round'v yopening fronrthebottle into'a narrow but high passage way, the flow gaging factor'of the deviceis'greatly' increased.: This, therefore, requiresicorrespond: ingv decrease in skill. of. the dispenser. He. can dispense accurately without'mu'ch eiort 'andcan' do it very.' quickly. Since the area of' the narrow but high passage wayisequal'to the roundopen.- ing from the bottle, a full capacity flow is avail'-V able, which can be instantly reduced by tipping down the body of the bottle, and then by the great latitude Aof gaging .provided bythe passage way, be easily manipulatedto therenementrequired. In a conventional round`spout,rth`e ,'w; of liquid is increased or reduced very,abruptly. by, a correspondingtipping ot the bottle, so-even. aY very.skil'fu1dispenser. willpour. too. much. or:V not enough, unlesshe takes considerabletima, In..the-` case oi-,apharmacisu whose. measuring ot'quantities is usually veryprecise,l thepOuring, oi liquids is a painstakingtandtime consuming,
